指導教授 : 林蒼祥
共同指導教授 : 蔡蒔銓

摘要


本研究運用2010年至2013年臺灣證券交易所之現貨資料,使用Lee et al.(2013)之內容做為虛掛委託單定義以及運用Cont et al.(2014)之內容中市場深度失衡變數(OFI)計算方式和Barber et al.(2009)中積極度變數(AI)計算方式來作為衡量方法,篩選出臺灣股票市場內之虛掛委託單。 根據篩選方法篩選出之虛掛委託單,本研究將以其揭示在五檔後對股票市場上投資人委託積極度以及股價兩方面之影響來做相關研究。 本研究結論發現,當虛掛委託單出現在市場上時,市場投資人將會委託更加積極之委託單,尤其是以自然人為最。另外,虛掛委買單會在落後一期使得股價上漲,落後二期使得股價下跌,虛掛委賣單亦會在落後一期使得價格上漲,但在落後二期已對股價無顯著影響。
